We are moving house in a few weeks and my kids have lots of wall stickers on their bedroom walls that I want to take off and use in their bedrooms in the new house. The issue is that I threw out the backing- paper that I unpeeled them from when I first bought them a few years ago! What on earth can I stick them on for a couple of weeks, that they will then happily peel off again when it's time to put them on the new walls? We want to paint the bedrooms when we move in so they'll need to sit somewhere for a few weeks before going up on the walls again. Any ideas???
